Carpule to Store Lower Dosage Amount of Dental Anesthetic

Abstract

A carpule to store lower dosage amount of dental anesthetic solution includes a tubular extrusion, a stopper, a front cap, and a color-coded band. The front cap is connected with a front opening of the tubular extrusion while the stopper is slidably engaged with a rear opening of the tubular extrusion. An inner diaphragm of the front cap is exposed through a central opening of the front cap so that the dental needle can be traversed into the tubular extrusion through the inner diaphragm. Additionally, the cross-sectional diameter of the central opening is similar to the cross-sectional diameter of the front opening so that the front cap is able to provide an expanded surface area for the dental needle to traverse through.
